If you mean delete the photos, yes, you can delete them if you have them safely stored elsewhere. However, you may need to either store them in a folder where iCloud cannot "see" them, or else turn off iCloud syncing of photos, otherwise they may reappear on your phone.
Also consider optimizing storage if you need space.

"With Optimize Storage, smaller, space-saving photos and videos are kept on your device while all of your original, full-resolution versions are stored in iCloud."
